Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and idempotentHint=true. The description adds the scope 'previously stored memory' and clarifies it targets data 'the agent saved earlier,' but it does not disclose permanence, error behavior (e.g., missing key), or any side effects beyond what annotations convey.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
